Patent CA-2282927-C (CA)
Title: Method of controlling the diameter of a clear extruded tube
Inventor: NIELSEN NIEL EDWIN
IPC: A22C13/00
Filed: 1999-09-21
Granted: 2004-11-30
Abstract: A method and apparatus for controlling the diameter of a clear extruded molten tube wherein the extruded tube contains a volume of a clear liquid and the level of the liquid is indicative of the tube diameter so the level rises as the tube diameter decreases. A light beam passing through the tube is refracted from a straight line path when the liquid level rises above the level of the beam. The refracting of the beam in turn triggers the introduction of air into the extruded tube to increase the diameter of the extruded, molten tube.

Title: System and method for dynamically increasing the capacity of a code division multiple access radio telecommunications network
Inventor: RAHMAN MOHAMED ANISUR
IPC: H04B7/26
Filed: 1998-04-16
Granted: 2005-09-27
Abstract: A method and system for dynamically increasing the capacity of a code division multiple access (CDMA) radio telecommunications network. The method begins by the radio telecommunications network receiving a request for access to the radio telecommunications network from an entering mobile station. Next, a loud capacity monitor determines if the radio telecommunications network is fully loaded. When the radio telecommunications network is fully loaded, a network load processor releases one of a duplicate channel element (transceiver) used in the CDMA radio telecommunications network by one of the operating mobile stations. The network load processor then assigns the released channel element to the entering mobile station. The system includes a load capacity monitor to determine whether the radio telecommunications network is fully loaded. The system also includes a network load processor to reallocate duplicate channel elements from the operating mobile stations to the entering mobile station.

Abstract: A dual band antenna with a simple and compact structure includes an inductor, first and second rod-like radiating elements connected to opposite ends of the inductor, with dielectric material surrounding both the inductor and the joining portions of the first and second radiating elements on the respective ends of the inductor. A conductive housing surrounds the dielectric and supports the inductor and the joining portions of the first and second radiating elements. The housing and dielectric create a capacitance, so that an LC resonant circuit is formed in conjunction with the inductor. The LC  circuit is designed such that only one radiating element radiates at the higher band of the dual operating band, whereas both radiating elements radiate at the lower band.

Abstract: The multi-chambered bottle has two chambers (11, 13), for example, with openings (21, 23), which are disposed inside the neck (19). The opening (23) is disposed coaxially with the neck (19). This allows a closure (27) to be screwed or snapped onto the neck that is provided with a thread (20) or a snap bead. In the process, the attachment (43) penetrates the opening (23) in a sealing manner. This creates two channels (35, 37), which lead from the chambers (11, 13) to the outlet openings (39, 40). The outlet openings can be closed with the cap (42).

Title: Apparatus and method for preventing unauthorized circumvention of television program blocking function
Inventor: TAM TONY T
IPC: H04H20/76
Filed: 1999-10-08
Granted: 2003-12-30
Abstract: A method and apparatus for preventing unauthorized circumvention of blocking of television programs. The system of the present invention prevents an unauthorized person from circumventing the VChip blocking of a specific show or channel through tuning with the cable box. A controller monitors the vertical synchronization (VSyncs) of the video signal coming into the TV  (102). If a video interrupt is identified by the controller without the TV  sending an IR command to the cable box, the controller redials the cable box to the channel it was on before detecting the video interrupt. This hinders an unauthorized person from working around VChip blocking functions.

Abstract: L'invention concerne un système de retenue de tige pour des bandes transporteuses modulaires en plastique. Selon un mode de réalisation, les tiges de connexion (16), traversant les extrémités de liaison (20) emboîtées des modules successifs (11-14), chacune comprenant une rainure circonférentielle (34) ménagée dans un emplacement, destinée à recevoir une bague de retenue (22) située entre les extrémités de liaison emboîtées adjacentes, viennent se loger par encliquetage dans ladite rainure. La bague de retenue constitue un ensemble simple qui utilise les outils existants, et une tige de la bande transporteuse peut facilement être retirée par application d'une force brusque sur l'extrémité de ladite tige. Selon un second mode de réalisation, le système de retenue de tige possède des éléments de blocage (60) placés aux deux extrémités de chaque rangée de modules, ce qui forme les bords de la bande transporteuse. Un espace d'une largeur correspondant à environ deux ou trois extrémités de liaison s'étend latéralement à partir de l'élément de blocage, le module étant dépourvu de structure d'extrémité de liaison qui confinerait la tige dans ledit espace, à partir de la partie inférieure de la bande transporteuse. La tige est forcée à une configuration pliante permettant son introduction dans un module ou son retrait, à partir de la partie inférieure de la bande transporteuse, et présente une configuration normale sensiblement droite après son introduction dans ledit module. Selon un autre mode de réalisation, la bande transporteuse possède une ouverture pratiquée à l'emplacement de la structure de blocage, alignée avec une série d'ouvertures d'extrémités de liaison, la tige étant préformée en une configuration courbe. Selon un autre mode de réalisation, les tiges possèdent chacune des têtes (114) situées sur une extrémité, ces têtes se trouvant dans la structure de blocage de la bande transporteuse assemblée.

Abstract: Due to the presence of various environment condition detectors in the home and businesses such as smoke detectors, carbon monoxide detectors, natural gas detectors, etc., each having individual but similar sounding alarm patterns, it can be difficult for occupants of such dwellings to immediately determine the specific type of environmental condition that exists during an alarm condition. The present invention comprises an environmental condition detector (10) using both tonal pattern alarms (85, 95, 105) and pre-recorded voice messages (90, 100, 110) to indicate information about the environmental condition being sensed. Single-station battery-powered and 120 VAC detectors are described as are multiple-station interconnected 120 VAC powered detectors. The pre-recorded voice messages describe the type of environmental condition detected or the location (50, 115) of the environmental condition detector sensing the condition, or both, in addition to the tonal pattern alarm. Provisions are made for multi-lingual pre-recorded voice messages (60).
